HUGO PEUCKERT, OF OEDERAN, GERMANY.

WEB-CUTTING MECHANISM.

Specification of Letters Patent.

Application filed January 7, 1911.

Patented Oct. 1, 1912.

Serial No. 601,449.

lb all whom it may concern:

Be it known that I, HUGO PEUOKERT, a subject of the German Emperor, and residing at Oederan, Saxony, German Empire, have invented certain new and useful Improvements in VVeb-Cutting Mechanisms, of which the following is a specification.

My invention has reference to machines for pasting cardboard-box corners, book covers, and the like, and relates in particular to the devices employed in such machines for cutting off the paper pasting-strip or web.

In such machines the work on the so-called anvil or support is covered with gummed paper. The latter is in the form of an end less web, from which a piece is cut off automatically in the desired length.

According to my invention I attain improved action by employing a slotted presser head and a correspondingly slotted work support, and by mounting below. the latter a spring-actuated rotary cutter, which is adapted to enter the slots therein.

One embodiment of my invention is illustrated in the accompanying drawings, which show only such parts of the machine as are necessary for the proper understanding of the construction and operation of the new contrivance.

Figure 1 is an elevation of the righthand side of the machine. Fig. 2 is an elevation of the upper part of the left-hand side of the same. Fig. 3 is a front elevation of the same. Fig. A is a vertical section through the anvil. Fig. 5 is a detail view showing a grooved cam to be hereinafter referred to.

At the top of the framing a there is mounted the vertically reciprocating presserhead 1;, controlled by a spring 0.

From the framing there extends the socalled anvil or work-support, consisting of a hollow arm d, whose top 6 is of ridge-shape, and which presents at the side an opening f, through which access can be had to the interior.

Below the support cl is a guide-arm g for the foot of a fork h. The latter carries a shaft 2', on which there is mounted a cutterdisk 70, controlled by a spring m, secured at the one end to an adjustable collar 02 and bearing with its other end against the boss Z of the cutter-disk.

The support d is provided with a num ber of slots 0, registering with other slots 7) in the resser-head b.

In the framing there is mounted in a stationary bearing a short shaft q carrying at one end abevel gear 1", while its opposite end is connected with the shaft z' by a member 8 having knuckle-joints at the ends.

w is a-fly-wheel, on whose shaft there is 1: 5

mounted, within the framing a, a spur wheel a, meshing with a pinion y.- This latter is coupled with a bevel gear a, which engages with the bevel gear 9". The fly-wheel w is connected by a rod Q) with a treadle lever t having its fulcrum at u.

At the left-hand side of the framing or there is mounted on the flywheel shaft a disk 2 having a cam-grove 3 (Fig. 5). 4c is a bent lever fulcrumed to the framing a at 5, and having its upper arm connected to the presser-head b by a pin and slot joint. The lower arm of the lever A is provided with a pin 6, which engages in the camgroove 3 of the disk 2 and also in the slot at the end of the one arm of a bent lever 7, fulcrumed at 8 to the framing. The opposite end of this lever 7 is connected by a pin and slot joint with the foot of the fork h.

To commence working, the cutter is must first be adjusted in position to suit the length of paper required. This can be done by loosening the collar 0?. and disconnecting and drawing out the shaft 2' forwardly, whereupon the cutter is can be set in the desired slot 79. The shaft 2' is then pushed in and secured in place again, and the collar 91 tightened. The collar must be so set that the spring 7% presses the cutter tightly to the edge of the slot, in order to produce a shearing cut.

The paper web 9 is now fed below the presser-head b by suitable mechanism, which forms no part of the present invention and therefore need not be described.

The treadle t is then depressed whereby the fiy-wheel 'w is rotated, its motion being transmitted to the shaft 2', causing the cutter is to revolve. The motion of the fiy-wheel shaft is also transmitted by the cam-disk 2 to the levers 4 and 7, whereby the presserhead I) will be moved downward, while the foot h with the rotating cutter k will be elevated, and the cutter leaving the slot 0 will sever the web 9.

Having thus described my invention, I declare that what I claim as new and desire to secure by Letters Patent is 1. In a machine for pasting cardboardbox corners, book covers and the like, in comciprocating the presser head and the cutter shaft with counter motion.

2. In a machine for pasting cardboardboX corners, book covers and the like, in combination, a work-support having :1 p111- rality of parallel vertical slots, a horizontal rotatable shaft located below the same, a

spring-actuated cutting-disk slidably mounted on the shaft and adapted to enter the slots, a presser-head presenting a plurality of slots in alinement with those in the worksupport, a carrier in which the shaft is slidably mounted, and means for Vertically reciprocating the resser-head and the cuttershaft simultaneously with counter motion.

In testimony whereof I ailix my signature in presence of two witnesses.
